A Fibre-to-SCSI address conversion

Disks connected with Fibre Channel display as SCSI disks on UNIX hosts. Disks connected with

Fibre Channel connections can be fully utilized. RAID Manager converts Fibre Channel physical

addresses to SCSI target IDs (TIDs) using a conversion table (see Figure 9 (page 51)).

Table 14 (page 51) shows the current limits for SCSI TIDs and LUNs on various operating systems.

If ISCSI, AL_PA is fixed a value 0xFE.

Conversion table for Windows. The conversion table for Windows is based on conversion by an

Emulex driver. If the Fibre Channel adapter is different (for example, QLogic, HP), the target ID

that is indicated by the raidscan command may be different from the target ID on the Windows

host.

Example 6 “Using Raidscan to display TID and LUN for Fibre Channel devices” shows an example

of using the raidscan command to display the TID and LUN of Harddisk6 (HP driver). You must

start HORCM without the descriptions of HORCM_DEV or HORCM_INST in the configuration

definition file because of the unknown TIDs and LUNs.
